Upland Hardwood Forests
General Hardwood Forests with Isolated Pools
Habitat Overview Members of this habitat all require isolated, non-alluvial pools for at least breeding purposes or for year-round residency. These include various types of depression ponds, usually without natural inlets or outlets connecting them to perennial streams; where such connections exist, they are intermittent, with breaks in flow that effectively isolate the pools. Some of the members of this habitat use these sites solely for larval development, leaving the wetlands as adult and returning only to breed. Others maintain their connection to these sites as adults. Plant members of this habitat are obligatorily associated with these wetlands.

These are wetlands that can occur in otherwise upland landforms, including ridge-tops. We also include, however, floodplain pools that are isolated from most flood events, drying out during dry periods and, like the upland examples, incapable of supporting a permanent population of fish, a main factor for many of the amphibians and invertebrates characteristic of this habitat type.

This particular habitat type contains generalized species that are not strongly limited by temperature regime and are found in two or all three of the main physiographic provinces in the state. These species are associated primarily with hardwood forests, including dry or mesic stands but also at least some floodplain examples. The amphibian members of this habitat group range out from the wetlands to varying extents, foraging or dwelling in underground burrows or under hardwood leaf litter or fallen logs.

This habitat type is associated primarily with non-sandy substrates and rarely experiences any burning. A group of species similarly dependent on isolated wetlands but associated with Longleaf Pine and other fire-maintained habitats is treated as a separate habitat type.

Related NHP Natural Communities NHP Natural Communities that represent the wetland portions of this habitat type include Upland Depression Swamp Forest, Upland Pool (Typic Piedmont Subtype), Upland Pool (Pleasant Grove Subtype), Upland Pool (Roberdo Subtype), and Upland Pool (Mountain Subtype). These communities are defined based on their vegetation, none of the species of which show a high fidelity to isolated pools.

Candidates for Inclusion Oophila amblystomatis (probably two or more species), which is a group of symbiotic algae that only live on the egg membranes of wood frogs and spotted salamanders (and other Ambystoma outside of NC).
